I
ADJUSTMENTS
Record- Playback Head Azim uth
l. Thread a standard test tape on the recorder.
2. Connect an output meter to the output of the re-
corder.
3. While playing back the I0,000 cycle tone, adjust
the Phillips head screw at the rear of the head
mount until peak output is obtained.
4. Check the output of the second channel. If the
output varies too much between channels, adjust
to give best results on both channels.
BeltFlipper(ll4)
If the belt flipper (114) is too low, loosen the set
screw and raise it so it wiII not rub the capstan drive
belt (71). If too high, Iower so the lift-off finger on
belt flipper will not rub belt.
Cut-0ff Switch
l. Place the recorder in a vertical position.
2. Loosen the thumb nut on motor capacitor assem-
blv.
3. Place the retractor post on cut-off arm (48) so
it is one-eighth of an ineh from the head cover
( B).
4. Tighten thumb nut.
5. With the recorder in the Play position and re-
corder setting in a vertical position, the pres-
sure of the tape contactor against the tape should
be enough to support the weight of a one cent
piece resting on the retractor post.
6. Make sure the cut-off arm shaft assembly has
.005" end play in its bushing.
Spindles
I. To align the spindles in the sides to side direc-
tion, loosen or tighten the two screws at the
bottom, toward the center oi the deck.
2. Place a l0 L/ 2" reel on each spindle.
3. Adjust the top screw until the reel runs free of
both flanges. This adjustment is for top to
bottom plane.
Stopping Brakes
l. Loosen the screw through the slotted hole in the
anchor bracket (165) and move the anchorbracket
for the initial adjustment.
2. Bend the brake adjuster tab on brake band as-
sembly (145 or lll) with a pair of pliers, to cause
the brakes to come on sooner or vice-versa.
Care must be taken to insure both brakes are
adjusted eqr-rally.
Take-Up Tensioner ( 24)
l. Leave .005" end play between the eccentric (81)
and bearing (83).
2. Position the take-up tensioner (24) so it will be
at a 30 degree angle with respect to the tape
deck.
Supply Drag Brake
l. Adjust the drag pulley bracket (l5a) so the ten-
sion spring (I52) will be stretched approximately
5/32" when in the play position.
Take-Up Torque
l. Place a ?" reel on the take-up spindle.
2. Place the recorder in a vertical position.
3. Fasten a L-L/2 ounce weight, such as a tire
. balancing weight, to the outer edge of the reel.
4. Place the Tape Control lever in the Play posi-
tion.
5. If the take-up torque, 'which should be 4 to 6
ounces, does not balance out ihe effect of the
weight, slide the metal clip on the idler carri-
age (107) closer tothe take-up spindletoincrease
the spring tension.
Rewind Torque
l. Place a ?" reel on the supply spindle.
2. Place the recorder in a vertical position.
3. Fasten a 4-ounce weight, such as a tire balanc-
ing weight, to the outer edge of the reel 90 de-
grees from the vertical axis. The weight will
exert a downward force of 13-inch-ounces. The
re'wind torque should be 12 to 13 inch-ounces.
Record Switch Latch
If the pressure arm (22) does not latch properly
with the switch, bend the endof the pressure armpast
the notch until they latch properly.
Pressure Roller
l. Place a loaded ?" reel on the supply spindle.
2. Place the recorder in a vertical position.
3. Fasten a4-ounce weight, such as a tire balanc-
ing weight, to the inside edge of the reel.
4. Turn the power on and place the Tape Control
lever in the Record position. The 4-ounce
weight should balance out the capstan pu1l. If it
does not, proceed as follows:
a. Loosen the lock screw on the pressure arm
(22).
b. Turn the6-32 Allen head set screw until the
4-ounce weight and capstan pull is balanced
out. Make this adjustment with tape running
through the recorder.
c. Retighten the lock screw.
